Your table will not display the new data unless you update the model using the appropriate model methods. Are you doing that?
If yes, please post a sscce code which demonstrates your problem.
Note: Please do take out time to visit the link I provided to find out what sscce really means.
Please read my reply carefully.
I had asked you if you are updating the model with the new values. All you have told me is you had forgotten to create the model and a bunch of code which is not SSCCE.
If you cannot take efforts to help us help you, I do not see what else can be done.
